Despite the fact that shoppers descended upon stores after giving thanks, Black Friday wasn't without its share of brawls. Here's a list of violent cases reported across the USA:

1. In Rialto, Calif., a police officer was injured trying to defuse tensions in the parking lot of a Walmart over shoppers said to be cutting in line. The incident happened around 7 p.m. local time on Thanksgiving. At least three people were involved in the fight and two were taken into custody, Sgt. Nicholas Borchard of the Rialto Police Department told NBC Southern California.

"The officer was struggling with the subject as he got into the car, and then the car started to move as the officer was partially inside the car. The officer was dragged quite some distance. He couldn't get out," Romeoville Police Chief Mark Turvey said.

4. In New Jersey, a shopper was pepper-sprayed and arrested Thursday evening. A heated dispute with a fellow shopper over a television led to an argument with a Walmart manager. After the manager called for help, the shopper attacked an officer, police told NBC New York . The shopper was charged with aggravated assault of a police officer, resisting arrest and disorderly conduct, Lt. Martin Gray told The (Newark) Star-Ledger.
